CFtpConnection Class

1.链接http://technet.microsoft.com/zh-cn/office/2kywsafk(v=vs.80)

2.测试ftp可以用这个地址：ftp://ftp.microsoft.com

以下是例子：

ftp连接

host==网站或ip

CInternetSession session;

CFtpConnection *connection=NULL;

m_out+="正在连接"+host+"\r\n";

UpdateData(FALSE);

try

{

connection = (CFtpConnection*)session.GetFtpConnection(host);//,_T("liaocheng"),_T("liaocheng"),21);

}

catch(CInternetException *err)

{

connection = NULL;

err->Delete();

}

if(connection)

{

connection->SetCurrentDirectory(_T("//bussys"));

BOOL bReturn = connection->GetFile(_T("readme.txt"),_T("readme.txt"));

m_out += "已连接上 \r\n";

CString line;

connection->GetCurrentDirectory(line);

m_out += "缺省目录为";

m_out += line +"\r\n";

connection->Close();

delete connection;

}

else

{

m_out += "无法连接 \r\n";

}

UpdateData(FALSE);

pFtpConnection ->GetFile( sTemp, sLocalTemp, true, FILE_ATTRIBUTE_NORMAL, FTP_TRANSFER_TYPE_BINARY, 1);//下载文件

得到文件大小

ftpFinder.GetLength();

http连接

CInternetSession session;

CInternetFile *file=NULL;

m_out += "正在连接"+URL+"\r\n";

UpdateData(FALSE);

try

{

file = (CInternetFile*)session.OpenURL(URL);

}

catch(CInternetException *err)

{

file = NULL;

//这个函数检查堆上是否创建了CException object

//如果创建了，就删除该对象

err->Delete();

}

if(file)

{

m_out += "已建立连接!\r\n";

CString line;

for(int i=0;i<20&&file->ReadString(line);++i)

{

m_out += line +"\r\n";

}

file->Close();

delete file;

}

else

{

m_out += "本地址没有发现http主机 \r\n";

}

UpdateData(FALSE);
